AUTOMATIC WEIGHING=WACHENE- SPECIFICATION forming part of Letters Patent No. 607,463, dated July 19, 1898.

Serial No. 649,417. u (No model.)

To @ZZ whom it may concern,.-

Be it known that l, FRANCIS Il. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Automatic leighing-Machines, of which the following is a specilication.

This invention relates to an automatic weighing-machine of that class in which an overload is iirst supplied to the load-receiver or bucket and in which the surplus material is subsequently removedto bring the loadreceiver or bucket to a true poise, and after which the load-discharger or closer of the loadreceivcr is opened and the completed load discharged, as described, for instance inLetters Patent of the United States No. 572,067, granted to me November 24, 1806, to which reference may be had.

One object of my present invention is to provide an vimproved automatic weighingmachine comprehending a load-receiver or bucket having a surplus-discharger and a surplus-receiver, a rotary surplus-conveyer supported in operative relation with the surplus-discharger and surplus-receiver, and an overload-supplying means including a chute and a material-driven power-transmitter supported below said chute and shiftable in av plane transverse to its path of rotation, and which power-transmitter is operatively connected with and is effective for rotating the conveyer.

A Afurther object of my present invention is to furnish a weighing-machine comprehending a rotary conveyer and a reciprocatory load-receiver set side by side and movable in parallel planes and each of which includes means for transferring` material to the other, andthe construction, organization, and operation are such that the transfer of material to each other will take place alternatively.

A further object of the invention is to furnish an automatic weighingmachine embodying improved overload-supplying means including` a material-rotated power-transmittin g stream-controller, improved load re.- ducing and resupplying means including a rotary conveyer in geared connection with and operated by the power-transmitter, and

Y material to the load-receiver.

improved means for controlling the operations of the several elements of the overloadsupplying and overload-resupplying means.

In the drawings accompanying and forming part of this specification, Figure 1 is a front elevation of a weighing-machine embodying my present improvements. Fig. 2 is a side elevation of the weighing-machine, illustrating the rotary power-transmitter in the position it occupies during the supply of material to the load-receiver and showing the load-discharger or closer members of the loadreceivcr in their normal closed positions, the load-receiver being in its normal load-receiving position.

Figs. 11.1: and l5 are sectional views, taken in line e e, Fig. l, of the lower portion ol' the weighing-machine and illus trate, respectively, two successive positions ol the loadsdischarger or closer, Fig. .ll showing the discharger in its closed position and Fig. l5 the discharger in its open or load-discharging position. Fig. 1G is a cross-sectional View of the machine, taken on dotted line tu fr, Fig. ii, illustrating the beam mechanism employed.

Similar characters designate like parts in all the ligures of Vlhe drawings.

'lhe framework for supporting the operative parts of the machine maybe of anysuitable construction, and it is shown consisting of two end frames or columns 2 and. Ll, mounted upon a chambered supporting-base 3, into which the completed loads are discharged from the load-receiver or bucket, said columns 2 and t being surmounted by the top plate 5 in the usual. manner.

For sustaining the bucket l have shown beam. mechanism ot the duplicate class similar to the weighing mechanism in the patent hereinbelore re [erred to,which weighing mechanism, briefly described, consists ot the counterweighted scale-beams .l and l', i'ulcrumed on the base i) and provided with suitable knife-edges on the poisingends thereol' lor supporting said bucket. Eachbeam is shown conilirising two counterweighted parallel beam-arms,and. the arms ol onebeani are shown in the present instance connected with those ot' the other beam at the inner end by links 23', which engage oppositely-disposcd knife-edges Carried by said beam-arms. rlhe beztm-arms ol' one beam are shown connected together by a tubular shaft or connecte 5', whereas the counterweighted beam-arms ol' the other beam are disconnected, so as to leave the i'ront ol the machine unobstructed for the operation of instrumentalities hereinafter described.

The bucket or load-receiver (designated by G) is of the single-chamber77 class and. is el' su bstantially the same generalconsl ruclion as the load-receiver (lescribet'l in my contemporaneously-pending aipiplical-ion, Serial No. (i-lS,O3f), filed iMigust l2, i807,

The term cbucket as herein employed signilies any suitable :form olf lozul-receiym' and should be so read in connection with the claims. The bucket is shown furnished intermediate its receiving and disclutrging ends with two conduits or spouts G and 7, which communicate through a side wall thereof with the interior of said bucket and are located oneaboreandatene side ol' the other. These conduits, on account ol' their functions, are res spectively termed the surplus-iflischarger an( surplus-receivcr.

rl`he lower or surplus-receiving conduitl is shown somewhat in lthe nature ol` a chute open at its upper end, and the upper conduit e' is shown furnished with a grayitative valve S, which is pivoted thereon and `is adapted l'or controlling the discharge ol' material through this conduit, said valve being' normally retained in its closed position byits own weight and having a projection il, adapted to cooperate with the valve-aetuator during the descending movement ol the bucket, whereby said valve may be opened.

As a means for actuating the valve 53, which lor convenience will be termed the load-re rducing Valve, l have provided. a ValVc-actuator, which, in the preferred form thereof shown most clearly in Fig. .l, is in the nature ol' a li.\'.ed arm lO, the outer end ot which is located in the path ol? Vertical increment of a projection J on the valve S, said actuator lO being preferably Yllxed to a stud l2, supported on the lrzimework.

The eyerload-supplying means, in the prelcrred forni thereol' shown in the accompanying drztwings, con'iprises a supply hopper or chute il, supported above the load-receiver and preferably forming a part ol.' the top plate 5 of the trammvork, said chute having at the discharge end and at one side thereol' a curved depending closer-plate 1li) and a combined power-transmitter and stream-eontroller (designated by l) and shown hereinv as a muliicompartment oversluit po\\"i;\/1.'-wheel) pivotally supported [for rotation.below the supplychute in such manne' as to be capable ol movement in opposite directions ttm'ard and away l'rom the closer l and. in a plane intersecting the line of llow ol the nn'iterial.

As a convenient means lor supporting the power transmitter or wheel 'l for rotative and diametrical movement l have `lufoviiled. a powf'eim'lieel carrier l", which, in the prevl'erred form shown in the drawings, is in the nature ol' a bracket ljufelferably supported l'or oscillatory movement on the shal't ll, journaled in lniarings on the framework, and

which bracket has outwardly-extending arms 15 and 15', in the outer ends of which is journaled the shaft 1G of the power-wheel. This power-wheel carrier is also shown furnished with a counterweighted arm 17 for shifting the power-wheel into a position for closing the discharge-outlet of the supply-chute and with its periphery in engagement with the inner face of the curved closer-plate 13, said counterweighted arm constituting an actuator for shifting the power-wheel in one direction. The power-wheel is shown having a multiplicity or circuit of circuinferentiallydisposed compartments open at their outer ends and closed at their inner ends, and the closer-plate 13 is so disposed relatively to the power-wheel that when said wheel is in position for closing the discharge-outlet of the supply-chute it will cover the open ends of the lled compartments of said power-wheel and prevent the escape of material therefrom and thus out off the supply to the load-receiver. (See Fig. 13.) For the purpose of shifting the power transmitter or wheel P in an opposite direction, or into the position shown in Figs. 2 and 11, whereby the same may be rotated by the impact of material discharged from the supply-chute, and at the same time facilitate the supply of material to the load-receiver or bucket, I have provided an auxiliary actuator 18, (shown in the nature of a counterweighted lever,) fulcrumed at 1S' on the load-receiver near the upper end thereof and having a bearing at its non-counterweighted end against the under side of the counterweighted lever 17 and adapted, as hereinbefore described, for elevating said eounterweighted arm. These two counterweighted actuators 17 and 1S are reciproeally effective in their operations for shifting the powentransmitter in opposite directions alternately. The lever or actuator 1S is constructed, disposed, and counterweighted to normally overcome the resistance of and thus tend to elevate the counterweighted actuator 17.

For convenience the opposing diametrical movements of the power-transmitter may be herein termed the opening and closing movements, respectively,thereof, the openin g movement signifying a movement of the power-transmitter from the position shown in Fig. -LL toward the position thereof shown in Fig. 2 and the closing` movement signifying a movement of said power-transmitter toward the chute-closing position. (Shown in Fig. 4.)

For the purpose of blocking the power transmitter or wheel against opening movement during the discharge of material from the load-receiver interlocking instru mentalities are provided in connection with the loaddischarger of the load-receiver, which will be hereinafter described.

The load-receiver or bucket G is provided at the lower end thereof with a load-discharger, which, in the preferred form thereof shown in the drawings, comprises two opposite and obliquely-disposed closers or closerplates L and L', which are shown pivotally supported at their-outer ends on links 2O and 21, respectively, which in turn are pivotally supported at their upper ends on brackets secured to the opposite side walls of the loadreceiver, and two opposing regulators (designated in a general way by M and M') pivotally supported at their upper ends at 22 and 22' on the load-receiver and pivotally connected at points intermediate their ends, as at 23 and 23', to the inner ends of the closers L and L', respectively, said regulators being furnished with counterweighted actuators 24: and 24', respectively, for normally imparting closing movements t0 the regulators M and M' and the closers L and L' simultaneously. Each regulator, in the preferred form thereof illustrated most clearly in Figs. 1, 7,

and 9 of the drawings, comprises a verticallydisposed angular blade extending the entire width of and below the closer to which the regulator is pivoted and two vertically-disposed angular eounterweighted arms extending upward from opposite ends of said blade and pivotally supported at their angles on studs extending from opposite sides, respectively, of the load-receiver, as shown in dotted lines in Fig. 1.

As a convenient means for preventing an opening movement of the load-discharger when the material-actuated power-Wheel is in its rotating position, and also prevent an opening movement of the power-transmitter when the load-discharger is open, Ihave provided in connection with the counterweighted actuators 24c and 24C' of the regulators M and M' and in connection with the power-transmitter carrier two reciprocally-effective stop devices S and S', the former of which is operative with the transmitter-carrier and the latter of which is connected with the regulators M and M' of the load-discharger.

The stop device S' comprises a stop member 2G (herein shown as askeleton segmentdisl; pivotally Vsupported at 27 on and at the upper end of the load-receiver and having a depending latch-engaging arm 2S) and a closer-sustaining rod 29, pivotallyeonnected at its yupper end to the stop member 2G and shiftably connected at its lower end to inwardly-extending arms SO and 30' on the regulators M and M', these arms being preferably bifurcated at their inner ends, and the lower end of the sustaining-rod having a pin seated in the bifurcated ends of said arms, this construction facilitating a free movement of the regulators and providing for the varying positions thereof and facilitating an unobstructed operation of all the parts.

The stop device S is shown-in the nature of a segment-disk fixed to the power-wheel carrier and having a stop-face 32 in concentric relation with the axis of movement of said carrier and in position for cooperating with the stop member 2G to prevent the opening IOO IOS

f comes movement of the loat'l-discharger when the parts are in the positions shown in Fig. 2.

As a means for normally holding the stop member 26 against accidental movement and until the loz'Ld-receiver arrives at a predetermined point i u its reciprocatory movement l have provided a counterweighted latch O, having a catch 33 at the inner non-counterweighted end thereof, which is normally held in engagement with the latch-engaging arm 2S, and as a means for actuating the latch to release the arm 2S and permit an opening movement of the closers L and L', Ihave provided a by-pass latch-tripper 35, pivotally supported on the framework of the nlachine, and which latch-tripper is furnished at the upper end thereof with a hook or projection 3U and at the lower end `thereof with a counterweight 257 for normally retaining the latchtripper in position for engaging' the non-counterweighted end of thelatch O during the ascending movement el the load-receiver,where by at a predetermined peint in said aseending movement said latch will be tripped to release 'the closers and permit the discharge of the completed load from the load-receiver.

ly comparison et' Figs. at and G of the drawings it will be seen that when the load-receiver has arrived at its truly-poised position and the latch O is tripped to release the closcrs L and L the stream -controlling power-transmitter will be in its chute-closing position andthe stop member 26 will be shifted on the opening movement et the elosers from the po sition shown in Fig. Ll.- to that shown in Fig. (3, thus blocking the opening movement of the power-transmitter, and, further, that during the ascending movement ot the load-receiver from the position shown in Fig. t to that shown in Fig. (j the non-counterweighted end of the actuator Il 8, which bears against the underside of the actuator 17, will be held by the looked actuator l? against upward movement, while its counterweighted end will be elevated to the position shown in Fig. o, in which position said actuator will remain until the completed load el the load-receiveris fully discharged and the elosers ll and L return to their normal closed positions, which throws the stop member 2G from the position shown in Fig. U to that shown in Fig. 2, thus releasing the stop device S ot the power-transmitter and permitting the counterweighted end of the actuator 1S to descend and thereby litt thel actuator l? and shii't said power-transmitter from the position shown in Fig. (3 to that shown in Fig. 2.

For the purpose ot preventing a premature closing movement of the power-transmitter the power-transmitter carrier is furnished with a depending by-pass arm 40, which engages a by-pass `:l-l, pivotally supported on the load-receiver, and which ity-pass holds said carrier against movement until the loadreceiver arrives at a predetermined point in its ascending movement.

The surplus receiving and resupplying apparatus eomprises,in the pretcrred iform there et illustrated in the drawings,an annular conveyer or translferring-rcceiver (designateffl by T) having' a multiplicity or circuit of circumferentially-disposed compartments, (each d esignated by 42,) which conveyor is supported at one side of the loada'eceiver l'or rotation in a plane paralled to the plane oi.' reciprocation oi' said receiver.

ln the ctmstruetion and organization shown in the drawings the conveyor or aunnlus is divided radially by partitions ll into a circuit of compartments J5, each ot which is open at its outer and inner ends, and said conveyer is so disposed with relation to the surplus-discharger f3 and surplus-receiver of the load-receiver that the surplus material will be discharged into the inner ends ol the lower compartments ot' the conveyor succes sivcly and will be carried by said compartments to and discharged into the surplus-receiver 7.

For the purpose ol closing the lilled compartments of the con veyerd u ring the rotz'ition thereof l have provided a curved closer-plate ett, which is fixed below and extends around the lower portion of the conveyor and is lfurnished at one end thereof wilh a discharge spout or chute 4:7, the lower end of which is in vertical alinemcnt with and is adapted to enter the open end ol the surplus-receiving conduit 7 of the load-receiver, this construe tion permitting the surplus material disq charged from thelonlsrcceiver to be deposited in the lower compartments ol' the conveyor upon the closer-plate, where it is advancer'l bythe partitionsot the compartmcnts during the rotation of the conveyor to a point where it is discharged through the spout #la7 into the surplus-recciving condn i t ol the load-recei ver.

By providing an annular conveyer supl ported for rotation in a vertical plane l am enabled to bring the outer ends ot the surplus-discharger and surplus-rcceiver in comn paratively close relation one at the inner and the other at the outer side ot the conveyor, thus materially economizingin space and l'acilitating the discharging l'rom and resupplying ot' material to the loz'ntreociver at points in very close proximity.

As a means li'or actuating the emlvcyer multaneously with the supply el the overload to the receiver, which in the present caso is preferable, l have provided actuating' mechanism directly controlled by the power-transH mitter. This actuating mechanism, in the preferred l'orm thereot' illustrated in the accompanying drawings, (':omprises a gear 5r), fixed to lthe conveyor in concentric relatifni therewith and meshing with an intermediate gear 5], pivotally supported in concentric relation with the axis ol' oscillation el the powertransmitter and meshing with a pinion 5i?, fixed to the shat't of said power-transmitter,

the construction and erganimtion et this actuating mechanism being such that during the rotation oi' the power-transmittcr l? the IOC) conveyer will have a rotative movement iinparted thereto.

From the foregoing description of the several operative parts of the weighing-machine and by reference to the accompanying drawings it will be seen that an overload is iirst supplied to the load-receiver suflicient to overcome the resistance of the beam mechanism and carry said receiver below its outer poising-line, that during the descent of the loadreceiver the power-transmitteris shifted from the position shown in Fig. 11 to that shown in Fig. 13, and after the same has arrived at the position shown in Fig. 13 and the loadreceiver is descending below its poising-line the load-reducing valve has an opening movement imparted thereto, thereby discharging the overload into the rotative conveyer. After suilicient surplus is discharged into the rotative conveyor to cause an ascending movement of the load-receiver to bring it to its true poisin g position, during which ascent the load-reducing valve is gradually closed, the latch O is tripped, causing an opening` movement of the closers L and L', thus discharging the completed load, and after the load is discharged and the closers are returned to their normal closed positions the power-transmitter is shifted from the position shown in Fig. 13 to that shown in Fig. 11, thus uncovering the discharge-outlet of the supply-chute and allowing the material to descend into the compartments of said power-transmitter and thence into the load-receiver, the gravitating material rotating said transmitter, which through the intermediate gearing imparts a rotative movement to the conveyer, causing said conveyer to advance the material contained therein to the point where it is discharged into the surplus-receiving conduit of said conveyer as a part of a new load, the rotation of the conveyer taking place simultaneously with the supply of the overload. This constitutes one of the cycle of operations of the cooperative elements of the weighing-machine and which operations are repeated in the order named.

Inasmuch as the rotary device P has twov functions, it constituting a power-transmitter or power-wheel for actuating the rotary device or movable conveyer T and also constituting a stream-controller, it will be understood that where this rotary device is termed the stream-controlling wheel in certain claims the power-transmitting function of said wheel does not necessarily enter into its operation; but where said rotary device P is referred to as a power-transmitter7 in said claims the stream-controllin g function in most cases enters into its operation.

Having described my invention, I claiml.
